Codex Hierosolymitanus (also called theBryennios manuscript or theJerusalem Codex, often designated simply "H" in scholarly discourse) is an 11th-century (1056) Greek manuscript. It contains copies of a number of early Christian texts including the only complete edition of theDidache. It was written by an otherwise unknown scribe named Leo, who dated it 1056.
Thecodex contains theDidache, theEpistle of Barnabas, theFirst Epistle of Clement and theSecond Epistle of Clement, the long version of theletters of Ignatius of Antioch and alist of books of the Hebrew Bible.
It was discovered in 1873 byPhilotheos Bryennios, themetropolitan ofNicomedia, in the collection of theJerusalem Monastery of the Most Holy Sepulchre inConstantinople. He published the texts of the two familiarEpistles of Clement in 1875, overlooking theDidache, which he found when he returned to the manuscript.
TheCodex's list of books of the Hebrew Bible has often been taken for the first written Canon of the Old Testament, dating from the early second century. However, Luke J Stevens argues that the list has notable parallels in spelling of the books and in its section title to the eighth-centuryDoctrina Patrum, which is itself dependent onEusebius.[1]
Adolf Hilgenfeld usedCodex Hierosolymitanus for his first printed edition of the previously almost unknownDidache in 1877.
